What radio are you using? I had horrible battery life with CM7 on the 5.12.00.08, but I switched to 5.08.00.04 and my battery has been fine. I'm not sure if that's the exact reason because I did a complete wipe of /data, /cache/, and /system, as well as reformat my sd-card before installing HBoot 0.35, the 5.08.00.04 radio, and the 2.3.3 ROM. I couldn't stand the lag and the constant reboots, so I switched to stock for now until CM7-Final comes out.

Thank you! I've been searching and searching for anyone on the interwebs with this same issue. Hopefully a solution can be found.

As soon as I (manually) upgraded to 2.3.3 on my Nexus One, the Android OS started to creep to near the top of my battery usage. Now, I can't make it through a day without recharging, whereas before I could easily make it through an entire day without concern.

I haven't installed any new apps, or enabled any new widgets.

Seems like the problem has gone away. May have been my bad: I left GPS on by mistake, and although I would've expected the phone to switch it off when I'm not doing anything, it may not have.

[Nexus One Q&A, Help & Troubleshooting] k_myk:
I'm not sure, but maybe battery drain which you encountered was related to froyo/gingerbread feature which backs up your settings and apps? I find gb eating my battery not worse than froyo. Well, actually I'm starting to think that it's even better.

FYI after 26h on battery "android system" is not even listed in "battery use" so it ate less than 1% of my battery. Nice:)

Hi all, I'm having the same issue with the battery here.

It is drained in a few hours even if I don't do anything with the phone.

This started happening after 2.3.3 manual update.

Same issue with battery on Android 2.3.3

Battery life was horrible on Android 2.3.3. It went from 70% to 35% overnigth (about 8 hours without using it). Android OS is consuming about 50% of battery when iddle. Before upgrading it only consumed about 10%.

With Android 2.2.2 I used to get about 48 hours of battery life.

I think maybe there is a bug in Android 2.3.3.

I to have had bad battery life since my manual update to 2.3.3.

I am running AT&T model.

The only programs I have changed since the update are

Protector by Alexander Kosenkov

Mobile Defense

DejaOffice.

I have uninstalled The Protector & Mobile Defense as a test.

Anybody else running these same programs & now having bad battery life?
[Nexus One Q&A, Help & Troubleshooting] shimsim:
Bump!

2.3.3 is definitely draining my battery much faster than 2.2

As others are reporting, Android OS has jumped up to the top on the battery usage page, around 30-40%, it used to be my display.

I have also noticed the GPS randomly turning on/off even though no apps are running that need it, so I disabled the GPS and this has improved the situation slightly but its still not great.

In terms of apps running, nothing that wasn't running perfectly fine prior to 2.3.3

Im running on stock everything:

BB: 5.08.00.04

BN: GRI40
[Nexus One Q&A, Help & Troubleshooting] spidermike0:
After uninstalling mobile defense& protector my battery life was back to normal& the android os was back down to a couple percent.

I reinstalled mobile defense & this had no effect on battery life or android os battery use.

I will reinstall protector app tomorrow& see if the problem reappears.

I read on the protector comments somebody else had same issue with battery life & isolated it to" protector" app.

So if you have this installed uninstall it& see if it helps.

2.3.3 Android OS is a thirsty beast ...

Hi guys,

I have the same problem.

- With 2.2.2: if I left the phone on overnight it dropped from 100% to 90% ( everything on except blutooth )

- With 2.3.3: it drops from 100% to 75 %, the culprit is android OS, it tops the battery usage with 68%

Im also having battery issues, running RC CM7, and have been looking around various releated forums this afternoon.

I've set the wifi sleep policy to never and also removed all of the apps i've installed other then GApps (Mail, Maps etc..).

Will see if that makes any difference, at the moment after 6 hours of the phone being on after a full charge i'm down to 77%. But the phone has just been sat on my desk only fetching push email from Company email and Gmail.
[Nexus One Q&A, Help & Troubleshooting] s.illes79:

I think the problem is from the Wifi only....
[Nexus One Q&A, Help & Troubleshooting] humpingdan:
I reset the davlik (Could be wrong spelling) cache from the Recovery screen, then restarted the phone.

I left Twitter, Mail and Gmail sync on as thats essentiall for me :) Setting the Wifi to Sleep = Never seems to help massively. I've now been tracking battery use over the last 2 hours:

13:42 = 75%

...

...

...

16:51 = 70%

Which means on standby just recieving Twitter, mail and Gmail updates via push I'm seeing a drop of 5% over a 3 hour period. Which of course is pretty wonderful :)

So I'm going to blame the wifi for now until evidence points otherwise.
[Nexus One Q&A, Help & Troubleshooting] decoyjoe:
Yesterday I posted that I too had issues with Android OS taking about 33% of the usage. But now the issue is gone. Android OS now sits at a nice 2% of usage.

I didnt change anything. Didn't uninstall or install any apps within that time frame. All I did was use my phone as I didn't have time to mess with it to figure out the issue. The only thing I did was restart my phone a couple of times. And then I went back to check the usage and Android OS settled back down to.where it should be, 2% of usage.

So my advice is to just be patient, use your phone, restart it here and there, and let Gingerbread make itself at home. Once Gingerbread is all settled, Android OS should back down to ~2% of usage.

That's my theory at least :-)

Current report.

I had removed 2 programs this weekend I thought might be a problem

Mobile defense & protector

I reinstalled Mobile defense yesterday with no additional battery problem.

I have now also reinstalled "Protector" app this morning. No more battery problems.

I do run an anti-virus program & it tells me when something is installed & it is safe.

I got a notice yesterday that an something android was installed & clean. I had not installed anything. I can't help but wonder if a fix was silently pushed out???

Anyway I am now enjoying android 2.3.3 Hope it stays that way.
[Nexus One Q&A, Help & Troubleshooting] decoyjoe:
I do have Wi-Fi always on, set to the turn off when screen off policy.

It is still on while I am enjoying Android OS at 3% of usage.

Like I said before, I didn't change anything on my phone. I just used it as normal and Android OS went back down to ~2% usage where it should be. And now my battery life is actually better than it was on 2.2.2 :D

So my suggestion is to just be patient and let Gingerbread do its thing before you do anything rash to solve the Android OS issue. :)
[Nexus One Q&A, Help & Troubleshooting] gdarren:
wifi sleep policy is probably the culprit

The idea about wifi being the issue seems to make sense. The battery is draining like crazy when I'm not using it and I've got my wifi sleep policy set to "when screen turns off".

I can definitely tell that manually toggling wifi on and off is making a difference in how quickly the battery drains. You can easily see it in the graph too. I'll play around some more and see what happens.

I hope that, like other posters, this will simply resolve itself in time.
[Nexus One Q&A, Help & Troubleshooting] kungfo0:
My N1 has been draining the battery about twice as fast since the Gingerbread update, "Android OS" being the largest consumer in the usage list.

However disabling Wifi didn't seem to help, and neither did disabiling GPS. For me it seems when I check "Use only 2G networks" things return to Froyo levels, but I need to do more testing to verify.
[Nexus One Q&A, Help & Troubleshooting] winfij:
I'm yet another example of the OS eating 65%+ of the battery after the manual update to Gingerbread.

Based on the comments here, I've switched my wifi from "when screen turns off" to "Never" and I'll see how it goes.

[Nexus One Q&A, Help & Troubleshooting] andydsm:
Hey guys,

As suggested by another user here, I rebooted my N1 and the problem seems to be gone now :)

The method to reboot I used was to switch off the phone and then power it on by holding the volume down button and the power button which brings up the recovery menu, then you have to find the "Reboot" selection I can't remeber where exactly it is, but it's there. After I did that, phone has been running for 14h 17min and batt level is currently at 68% and Android OS went from 45% usage down to 7% !

FYI I keep everything always turned on GPS, bluetooth (with BT headset connected all day), wifi (for wifi sleep policy is turn off when screen's off.) As well as yahoo mail app, facebook app, gmail app, rss feeds, weather etc.

The reboot made a HUGE difference on my unrooted phone, so anyone who has the battery drain issue I would suggest to try this out first :)

Mine seems to be getting better. At first I was lucky to make it through the day with very light use. Even last weekend it dropped from 100% to 71% in 1.5 hours and I only checked the time twice and the weather once. After installing setcpu and configuring a few profiles, I went down to 50% between 8am and 5:30pm with fairly heavy usage. (twitter and facebook for at least an hour, 3 (>5 minute) phone calls, 22 texts, and angry birds for about 30 min)
[Nexus One Q&A, Help & Troubleshooting] bobbyphoenix:
At first it was worse, but I noticed the sync kept popping up more randomly. I thought it was just going through its phases, but I was checking some settings, and it turned out my Twitter account keeps trying to sync like every five minutes even though I have it set to every hour. (I think with the new Twitter app it has some issues with sync), so I un-checked auto sync, and boom, I went from just getting through a day before recharge to two days easy. Coincidence? Maybe, but I think not. I now only have G-Mail to auto sync, and turned off all others, and I can go about two and a half days before needing to charge. I'm happy!

Battery life with the stock kernel wasn't good enough for me. So I moved on to a different kernel - Wildmonks http://wildmonks.whoisthedrizzle.com/kernel/2.6.35/010611/2.6.35.10_SVS-950mV_CFS_AXI_720p_1152MHz_010611.zip to be specific. Since then the battery life has been awesome :D Not only that; it also fixed another issue of slow USB transfer speed :) Now I easily get write speeds ranging from 2.3 - 4.5 Mbps with my Class 2 MicroSD card. Besides the kernel also offers the audio boost and 720p recording options ;) I suggest, all those having issues with the battery life and/or the USB transfer speed, give this kernel a shot.

I originally had the same issue but now after reboot, my battery life is AMAZING!!! At my school, much of it is a total dead zone for att, and if I left the radios on with 2.2, my phone would be at about 20ish% at the end of the day (9hrs). Today I didn't turn off the radios and although cell standby took 72% of my battery usage (with 59% of the time without signal), I had 70% battery at the end of the day with mild texting, surfing, and a call. WiFi off BT off, GPS on and checking weather every three hours, display at full brightness. Android OS at 2%. Gonna try with airplane mode and wifi next week (fridays are only 5.5hrs). CM7 RC1 though, so results may be different from stock because I am 2.3.2 not 2.3.3.
[Nexus One Q&A, Help & Troubleshooting] pwkpete:
Been hearing a lot of people have worse battery and some say better. (Can never tell if that's a one day opinion or just a short term impression.)

My experience over about a week is that it is significantly worse. Same usage pattern. In fact significantly less today - found the phone dead after 12hrs off charge. Didn't play games, no calls today, no GPS and just scanned some news and email as I was at my desk most of the day. Froyo was significantly better.

I've also had 2 hangups and one hard reset. I don't think I had a month with that on Froyo.

Granted there are a few niceties, but I don't think they did a good job testing this version out. I'll give it another week, but so far I'm unimpressed from a daily usage standpoint.

Oh and the green icons suck too, give some color options... What is this the 70s and we're using green terminals? :)

So has there been any other news on this front? Or just a handful of people with issues?

My theory is that wifi isn't sleeping as it used to be. This gets reflected (oddly) as an increase is Android Os. With wifi on, battery usage reports 'Android os' sucking up 20 to 45% of my battery. (Regardless of wifi sleep setting)

With wifi manually turned off battery usage for 'android os' goes back to the normal 2%.
